[Section 1: Managerial Economics & Scarcity (Q1-10)]
Q1. What is the definition of opportunity cost in managerial decision-making?
A. The total cost of all resources used in production
B. The value of the next best alternative forgone when making a decision
C. The difference between total revenue and total cost
D. The explicit monetary cost of a business operation
Correct Answer: B. The value of the next best alternative forgone when making a
decision [CORRECT]
Rationale: Opportunity cost represents the value of the next best alternative sacrificed,
which is essential for managers to evaluate true decision costs. A confuses opportunity
cost with total cost, C defines economic profit, and D describes only explicit costs.
Correct Answer: B
Q2. A manager at a manufacturing firm is considering using company-owned
warehouse space for a new production line. The warehouse is currently leased to
another business for $8,000/month. In economic terms, this $8,000 represents:
A. An explicit cost of production
B. An implicit cost of using the warehouse
C. A sunk cost that should be ignored in the decision
D. A marginal cost of expanding output
Correct Answer: B. An implicit cost of using the warehouse [CORRECT]
,Rationale: The forgone rental income is an implicit cost because it represents the
opportunity cost of using an owned resource, not an out-of-pocket payment. A
describes actual cash expenditures, C incorrectly labels it as sunk (it's avoidable), and D
confuses it with incremental production cost.
Correct Answer: B
Q3. A small business owner invests $100,000 of personal savings into her company.
She could have earned 5% annual interest in a savings account. The business generated
$150,000 in revenue and had $130,000 in explicit costs. What is the economic profit?
A. $20,000
B. $15,000
C. $25,000
D. $5,000
Correct Answer: B. $15,000 [CORRECT]
Rationale: Economic profit subtracts both explicit and implicit costs from revenue; the
$5,000 forgone interest must be included. A is accounting profit only, C ignores explicit
costs, and D miscalculates the implicit cost.
Correct Answer: B
Q4. A supply chain manager analyzing production data notes that a manufacturing plant
is operating at a point inside its production possibilities frontier. This indicates:
A. Economic growth
B. An unattainable production combination
C. An inefficient use of resources
D. Full employment of resources
Correct Answer: C. An inefficient use of resources [CORRECT]
,Rationale: Points inside the PPF indicate resources are underutilized or misallocated,
representing production inefficiency. A describes an outward PPF shift, B describes
points outside the PPF, and D describes points on the PPF.
Correct Answer: C
Q5. A strategic planner for a developing nation observes that new technology has
increased factory output by 30% without additional labor. This corresponds to:
A. A movement along the production possibilities frontier
B. An inward shift of the production possibilities frontier
C. An outward shift of the production possibilities frontier
D. A point inside the production possibilities frontier
Correct Answer: C. An outward shift of the production possibilities frontier [CORRECT]
Rationale: Technological improvements increase productive capacity, expanding the
PPF outward. A describes changing product mix with fixed resources, B indicates
economic contraction, and D indicates inefficiency.
Correct Answer: C
Q6. A trade analyst notes that Country A can produce either 100 units of steel or 200
units of wheat using all its resources. What is the opportunity cost of producing 1 unit
of steel?
A. 0.5 units of wheat
B. 1 unit of wheat
C. 2 units of wheat
D. 200 units of wheat
Correct Answer: C. 2 units of wheat [CORRECT]
, Rationale: The slope of the PPF shows that 100 steel = 200 wheat, so 1 steel costs 2
wheat. A inverts the ratio, B ignores the trade-off magnitude, and D uses the total rather
than the per-unit calculation.
Correct Answer: C
Q7. A manager is deciding whether to produce one additional unit. The marginal benefit
of the unit is $120, while the marginal cost is $135. According to marginal analysis, the
manager should:
A. Produce the unit because MB > 0
B. Not produce the unit because MC > MB
C. Produce the unit because total revenue is positive
D. Not produce the unit because average cost exceeds price
Correct Answer: B. Not produce the unit because MC > MB [CORRECT]
Rationale: Rational decision-making requires producing only when marginal benefit
exceeds marginal cost; here the additional unit reduces net benefit. A focuses only on
benefit, C uses irrelevant total revenue logic, and D incorrectly applies average cost.
Correct Answer: B
Q8. The fundamental decision rule of marginal analysis states that a rational manager
should continue an activity until:
A. Total benefit equals total cost
B. Marginal benefit equals marginal cost
C. Average benefit equals average cost
D. Marginal benefit exceeds total cost
Correct Answer: B. Marginal benefit equals marginal cost [CORRECT]
